    Coulomb's law Law
AI Thread Summary
In the experiment with two aluminum foil balls, one charged and the other neutral, an unexpected attraction was observed despite Coulomb's law suggesting no interaction due to the neutral charge. This phenomenon can be explained by electrostatic induction, where the charged ball induces an opposite charge on the neutral ball, leading to attraction. Factors like humidity may influence the results, but the theoretical basis for the attraction remains valid. The discussion highlights the importance of understanding electrostatic principles in practical applications. Overall, the experiment demonstrates how neutral objects can still interact with charged ones through induction.

We were doing an experiment today and we had 2 aluminum foil balls hang next (but not touching) to each other. Both were initially grounded then we charged one of them while the other remained neutral. We observed an attraction between them but coulomb's law states that:

F = k(q1*q2/r^2). If one ball was neutral (zero charge) then it should result with no attraction nor repulsion. I realize that this experiment may have other influencing factors such as humidity but theoretically this assumption should be true right?

Do you know electrostatic induction?

This results in an opposite charge induced on the neutral ball, from the charged one, resulting in attraction.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
